<p>  <a name="smbjoin"></a><strong>10. Join the AD Domain</strong></p>
<p>Once the Kerberos and Samba are configured, it's time to add the pptpd server to the AD domain. For Samba version below 3.0.23:</p>
<blockquote>
  <pre>[root@pptp ~]# net ads join -U skwok@EXAMPLENET.ORG &quot;Asiapac/Australia/Sydney/Servers&quot;<br>skwok@EXAMPLENET.ORG's password: <br>Using short domain name --  EXAMPLE<br>Joined 'PPTPDSVR' to realm 'EXAMPLENET.ORG'
</pre>
</blockquote>
<p>For Samba version 3.0.23 or above:</p>
<blockquote>
  <pre>[root@pptp ~]# net ads join -U skwok@EXAMPLENET.ORG createcomputer=&quot;Asiapac/Australia/Sydney/Servers&quot;
skwok@EXAMPLENET.ORG's password: 
Using short domain name -- EXAMPLEE
Joined 'PPTPDSVR' to realm 'EXAMPLENET.ORG'</pre>
</blockquote>
<p>The above<em> net ads join</em> command creates the server in the container</p>
<p>"OU=Servers,OU=Sydney,OU=Australia,OU=Asiapac,DC=EXAMPLENET,DC=ORG&quot;</p>
<p>The user must have admin right on the container to create the server object. If the operation is successful, you will see a new server object created in the AD.</p>
<p>Another test to see if the trust between the pptpd server and the domain is working is  smbclient.</p>

<p><strong>Note</strong>: With Samba v3.0.14a or v3.0.20, everytime I run &quot;net ads join&quot;, the command crash at the end with message &quot;*** glibc detected *** net: free(): invalid pointer: 0x001cddb0 ***&quot; and then a dump to the screen.  The join seems to be working fine though. Samba v3.0.21a or above does not have this problem. </p>
